What steps will reproduce the problem? 1. Install GTalkSMS on any Android-Phone, configure it like below and connect to Prosody. 2. The server gets the connection request but doesn't do anything afterwards. What is the expected output? The user gets logged in or I get more details in the prosody server log. What do you see instead? GTalkSMS is stuck at "Waiting..." and retries the connection after a given time interval. The prosody server gets all the connection requests but doesn't do anything afterwards. With ejabberd as xmpp server and the same GTalkSMS settings there were no problems at all. What version of the product are you using? On what operating system?

I've set "c2s_require_encryption = true" in the options of prosody but also enabling PLAIN auth and unencrypted connections doesn't change anything. It also doesn't matter if the username or password are correct. It seems to be stuck before the authentication process. I localized the section in the source code (https://github.com/Yakoo63/gtalksms/blob/11d4388ff27e318f3e5e5aa1c76f25db8eb10b98/src/com/googlecode/gtalksms/XmppManager.java#L544) where GTalkSMS throws the error. Maybe someone can help me debug this any further as I don't know what to do next. Regards codiflow

Using a different XMPP server with ejabberd 20.03.68 as server software everthing works like it should.

Hi, thanks for the report Could you provide debug logs? In case this is related to #1560, does this happen with every password you try?

Hi Zash, > Could you provide debug logs? What kind of logs do you mean? All logs I got are already included in my bug report. > In case this is related to #1560, does this happen with every password you try? Thats a good question. I don't remember if I tried a different password but id doesn't contain any special characters. Its length is 24 characters with only upper- and lowercase letters and digits. So I don't think this should be any problem. Hope this helps any further.

The provided logs are only contain 'info' level messages. There's usually a lot more logged at the 'debug' level (see your logging config)

What version of the product are you using? On what operating system? GTalkSMS 5.0.1.84 (Source: https://github.com/Yakoo63/gtalksms/releases/tag/5.0.1.84) Prosody 0.12.0 (on Debian 10 (buster) After waiting for the new release 0.12.0 I tried to login again using GTalkSMS with debugging activated. The problem still persists and I don't know whats the cause.

GTalkSMS does not appear to be developed anymore. The referenced version seems to use the obsolete asmack build(system?) of the smack library from before smack worked on android. The problem was most likely in smack somewhere, hopefully it has since been fixed in later version. Given how simple SASL PLAIN is and how it works with other clients I don't think there is a problem on the Prosody side, so I will close this.
